Answer:
A researcher studies length of time in college, first through fourth year, and its relation to academic motivation. To get the most detail out of her measures, she assesses each student in both the fall and spring semesters of each of their four years in school. She finds that students have increasingly higher motivation from their first semester to their seventh semester (the start of their fourth year), with a trailing off in the last semester. The independent variable are:
- Semester in school
- Year in school
Step-by-step explanation:
- The dependent variable in the given scenario is academic motivation as she is researching on academic motivation so this factor is influencing the results.
- The semester and year in school are independent variables as these two factors are not influencing the results or research.

Because if you can do live by that you can do that bye-bye
The first row has 20 + 0 seats, the 2nd row, 20 + 1, 3rd row 20 + 2 . . . until 60th row has 20 + 59 (not 60 as the first row had 0 added on.
therefore you need to add up 20 + 21 + 22 . . . all the way to 76, 77, 78, 79.
79+ 21 = 100, 78 + 22 = 100, 77+ 23 = 100, in fact up to 49 + 51 = 100
That gives us 39 x 100 and add on the the other rows + 20 + 50
= 3970 seats
